GARFIELD H. CALEY, OF WATERFORD, WISCONSIN, ASSIGNOR-QF-ONE-TI-1IRD;TQ- HERMAN;J. HEMBROOK, OF WATERFORD, WISCONSIN CORN-SHOCK SLING.

Application filed November 10, 1916.

To all whom it may concern:

Be it known that I, GARFIELD H. CALEY, a citizen of the United States, and residentof lVaterford, in the county of Racine and State of lVisconsin, have invented certain new and useful Improvements in Corn- Shock Slings; and I" do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to new and useful improvements in hoisting slings, more particularly adapted for use in connection with corn stacks.

It is the object of the present invention to provide a comparatively simple and readily attachable sling member for corn stacks, which is adapted for engagement with a hoisting means whereby when the stack is hoisted and conveyed to a desired position, it may be dropped in a wagon or other receptacle, and which is provided with means for preventing slippage of the stack through the sling.

A still further object resides in the provision of a sling member including rigid jaw portions adapted for securement to gether to form the sling whereby said sling may be positioned about the stack withotr' the necessity of a person going entirely around the stack thus permitting a desired rapidity of operation, and whereby the stack may be dropped by releasing the securement of the jaws.

With the above and other objects and advantages in view the invention resides more particularly in the novel combination, formation and arrangement of parts more particularly hereinafter described and particularly pointed out in the appended claims.

In the drawings:

Figure 1 is an elevational View of a corn stack showing the improved hoisting means associated therewith.

Fig. 2 is an elevational view of the retaining fork with the associated structure shown in sections as indicated by the line 2-2 of Fig. 1.

Fig. 3 1s a transverse sectional view through the release structure of the retaining fork on the line 33 of Fig. 1.

Fig. 4: is a top plan view of a modified form of sling member.

Specification of Letters Patent.

Serial No. 130,530.

Referring now more particularlyv to the accompanying drawings, the sling member shown in Fig. 1 comprises a cable 5 carra ing at one end a pulley 6, and the other end of the cable is insertible between the pulley and a clutch pawl 7 carried by the pulley bearing arm, whereby the cable. mayv be tightly bound about the stack.

For securing the cable to the snatch block 8 of a hoisting rope 9 and: alsofor holding the sling against possible sliding movement on the stack, a fork 10 is pro-. videdv having the lower end. of its shank bifurcated, and pivoted between these fur: cations is. a hook barll which when disposed at an angle to the shank of the fork has its bill engaged between the furcations of the fork shank. The cable. 5 is adapted to be inserted between the bill and fork shank and may be thus securely held. To form a releasable. means for retaining the hook bar in this. holdingposition, a bar v12 extends diagonally outwardly from the in-, ner portions of the furcations of the fork shank and has its outer end bifurcated to forma recess adapted to receivethe outer end ofthe hook bar. 11, thisv recess being normally closed to retain the hook bar.there-. in by a pawl 13. pivoted to the bar 12and normally urged to extend its free enlarged end across the recess by a spring 14 mounted on a bolt 15 passed through the pawl and one of the furcations of the bar 12. A release rope 16 is secured to the free end of the pawl and thus when the stack has been lifted and conveyed to a desired position retraction of the pawl will permit the hook bar to swing to releasing position to drop the stack.

The hook of the snatch block 8 is engaged in a clevice 17 at the lower bifurcated extremity of the fork shank. Thus as the stack is hoisted the fork will be swung to press into the stack with the sling member as a fulcrum to thus positively prevent possible accidental detachment of the stack from the sling memher.

In Fig. 1 there is shown a modified form of sling member comprising a pair of substantially semi-circular jaws 18 pivotally connected at adjacent ends and each comprising a pair of plates convergent and tapered toward their free ends. For holding the jaws together to retain a stack therebetween a cable 19 is secured to one jaw, adjacent its pivotal end, and this cable extends across the pivot of the jaws inwardly thereof, and is wound on a Windlass 20 on the other jaw which is held against retrograde movement by a pawl 21 to which it is secured a releasing rope 22.

F or securing this modified form of sling member to the fork 10, chain sections 23 are attached to its intermediate portions and to a common ring 24; which is engageable in the hook bar 11. In this modified form of sling member the release of the stack is provided for by the pawl 21 and rope 22, and in this arrangement the pawl 13 would not be actuated to procure successive operations of the stack.

While the jaws 18 may be rigid throughout their lengths, I find it expedient to form jaws in outer and inner pivotally connected sections 25 and 26 respectively and to control the outer sections 26, links 27 are pivoted to the extended inner end 28 of the outer section 26 of one jaw and to the inner portion of the inner section 25 of the other jaw, the links thus being disposed in crossed relation and being preferably outwardly bowed whereby to conform to the general circular shape of the loop formed by closing the jaws. Thus an opening movement of the inner jaw sections will cause a relative outward movement of the outer sections 26, whereby a maximum space is procured between the outer ends of the jaws.

By this arrangement I find that it is possible to manipulate shocks of corn which have fallen onto the ground and become considerably disarranged. WVith the jaw secvtions rigidly connected to form rigid semicircular jaw portions this would not be possible, although such sem1-c1rcularjaw portions may be efficiently manipulated to engage the stacks when standing.

What is claimed:

1. A corn stack manipulating device comprising a stack securing means adapted to be positioned about the intermediate portion of a stack transversely thereof, a stack engaging member to be disposed longitudinally of the stack and in engagement with the outer side thereof, said member being in a plane positioned substantially at right-angles to the longitudinal plane passing through said securing means, a connection between the stack engaging member and the securing means, and means for lifting the stack, said means being attached to said member.

2. In a device of the class described, a pair of main j aw members pivotally connected together at one end, a supplemental jaw member pivoted to each of the main jaw members, each of said supplementaljaw members being pivotally connected intermediate its ends to the free end of one of the main j aw members, a link pivoted at one end to the inner end of each supplemental jaw member, said links being crossed and pivoted at their other ends to the main jaw members adjacent the pivotal connection therebetween, each of them being attached to the main jaw member remote from that to which its supplemental jaw member is pivoted, whereby movement of the main jaw members will actuate the supplemental jaw members, and means for holding the main jaw members against outward movement.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of WViscousin, in the presence of two witnesses.
